This invention relates to improvements in can washing machines and moreparticularly to a delivery mechanism therefor which is.

operative to receive the cans and their respective covers after thecleaning operation, to up-end the cans to an upright position, to

place the covers upon them and to move the covered cans to a positionwhere they may be readily removed by an attendant or otherwi e.

One object of the invention is a novel construction and arrangement ofthe various parts utilizedin the performance of the several. operationswhereby simplicity of construction and operation is obtained. A furtherobject is to provide a mechanism erated in timed relation with thecleaning equipment whereby the said mechanismis conditioned toeiiectdelivery of the covered. cansat the 'rate'they are cleaned.

The invention is illustrated in the panying'drawings, in which:- igure 1is a side elevation of the delivery mechanism showing the positionoi theparts lCCOHP .as they appear at the instant a cover is being applied toa can.

- The'delivery mechanism, as illustrated, is designed especially for usein connection with a machine for washing milk cans and the coverstherefor. As in general practice, the

ing machine and treated therein in the man 3 her des1red,'th1s'ispreferably accomplished by the machine which forms the subject'mat- '60"439,299, the discharge end of such a machine beng indicated.gen'erallyat Q. As illus-' tratechthere'fore, the cans 15 are movedthroughthe cleaning machine toward the delivery mechanism along railsupports 23 by fingers 17 between guide rails 16, the said fingers beingadapted to advance the cans;

the rail supports 23 step-by-step. Thecan covers 18 are, as shown, movedthrough the cleaning machine toward the delivery mechanism along anelevated guideway 19 by a chainQO, the latter being. provided withfingers 21 which engage the covers to push them along the said guideway.

' The delivery mechanism is adapted upon receiving a can and its cover,to up=end the former, after which operation it is moved w'hile'up-endedtoward the cover receiving position. The cover which is delivered to thedelivery mechanism has, in the meantime moved in'advance of the can andis sup ported in the delivery mechanism above the mouth of the can. Asthe latter is advanced the cover is lowered, the cover applyingmechanism and the can advancing means cooperating so that as the'canreaches the cover the mouth of the can. As the can continues applyingposition, the cover is lowered into i 28 respectively.

to move forward under the influence of the can advancing means, the cancarries its cover out of the cover applyng mechanism.

The mechanism by which the cans are upended as they are discharged fromthe clean ing machine includes a downwardly inclined support 22 whicharrange to provide an extension of the rail supports 23. (lo-operatingwith the support 22 is an inverted V-shaped member 24, one leg 25 ofwhich abuts the support 22 adjacent its bottom end, the said memberbeing adapted to provide a shoulder. When a can moves 0% the railsupports 23, it tips forward by gravity andthe lip thereof drops intothe corner provided by the leg 25 of the member 24; and the support 22.As the can continues to fall, its'breast drops upon the shoulderproviding member 2-1, whereupon the lip of the can leaves the positionit occupies and moves upwardly as the body of the can approaches ahorizontal position.

Means is provided for arresting the up ending movement of the can as itapproaches a substantially horizontal position. The said meansresembles, to some extent, a trough open at both ends, the downwardlyconverging sides of which are spaced so that their bottom edges delimita rectangular opening when in the can receiving position. One side 26 ofthe trough, as illustrated, is inclined slightly upwardly in thedirection of its front end and is preferably fixed against movement asby strap and angle members 27 and The other side 29 of the trough isdesigned for pivotal movement whereby its outer or free end may be movedtoward and away from the outer end of the fixed side member 26. To thisend, it is secured as by welding to an angle member 30 (see Fig. A) Thelatter carries a vertical stub shaft 31 which is mounted in a bearing32, the said bearing being suitably secured to a frame member 33, asbest shown in Figs. 5 and 9. A link is fixed to the end of the stubshaft 31 and at its opposite end the link is connected by a second link35 to a slide block 36. As illustrated in detail in Figure 10, thisblock is formed from spaced bars 87 to which are secured plates 38 whichoverlie channel members 39, the latter being supported by means ofdepending straps 40 from the frame of the machine, it being understoodthat the said channel members provide a guideway in which the slideblock 36 may move back and forth.

The slide block 36 is connected by a link 41 to the upper end of a lever42. The latter is supported intermediate its ends upon a pin 43 which ismounted in a suitable bearing block carried by a frame member of themachine. At its lower end, the lever 4:2 is connected by means of a rod45 to a lever 46, the latter being pivotally mounted at its lower end ina bearing block a7. The lever 46 carries a roller 48 which rides in acam groove &9 provided by a cam wheel 50. The cam wheel is mounted upona transversely extending shaft 51 which is connected through suitablereduction gearing to a drive shaft 52, the said gearing being indicatedby a sho-Wingof its casing 53 (see Fig. 2). It will thus be apparentthat as the cam wheel 50 is rotated the roller 48 travelling in the camgroove l9 causes the lever A6 to oscillate between determined limits.This movement is transmitted by the link 4.5 to the lever 42 whichcauses the slide block 36 to reciprocate in its guideway. As the slideblock 36 moves back and forth in this manner, it causes the free end ofthe side member 29 of the trough to move toward and away from the outerfixed end of the companion side member 26.

'The cam track 49 is so formed that the pivoted side member 29 of thetrough is moved to the position shown in Figure 3, e. g. substantiallyparallel to the companion fixed side member 26, at the instant that acan is moved as the ends of the rail supports 23. The pivoted sidemember 29 remains in this position for a period of time sufficient topermit the can to tip forwardly and be received between it and thecompanion side member in substantially horizontal position. As the canis supported in this posi' tion, the cam wheel 50 continues to revolvethereby causing the free end of the side member 29 of the trough to moveaway from the adjacent end of the fixed side member. The normal openingformed beneath the can by the side members of the trough is thus increased by degrees from an opening delimited by substantially parallelsides to one in which the sides diverge in the direction of the bottomof the can to a predetermined extent. It will be apparent that as thefree end of the pivoted side member 29 of the trough moves away from theadjacent end of the'companion side member, the bottom of the can movesdownwardly a short distance as it follows the sides of the trough.However, as the free end of the pivoted side member contimies to moveaway from the fixed side member, a point is reached where the can issupported beyond its center of gravity in the direction of its top. Whenthis point is reached, the can tips toward an upright position andslides downwardly between the side members of the trough. It is to beunderstood that while the can may be up-ended by the use of a singlepivoted side member as described, both side members may be pivoted ifdesired and in either case they function in substantially the samemanner.

As the can passes between the side members 26 and 29 of the trough, itis shifted bodily be a deflector plate 54 laterally of its previous pathof travel upon a second pair of rail supports 55, along which it ismoved on its bottom toward the cover receiving position. The

can is moved by a chain 56 which carries fin gers '5? whichengage theback of the can to push it along. The chain 56 may be driven by asuitable sprocket from the transverse shaft 5 1 From the reversingtrough, the can is guided along the rails on one side by-a guid'e'plate59 and on the other side by a guide bar 59a.

The cover of the canhas, in the meantime, moved out of the guideway 19of the cleaning machine into the delivery mechanism and is supportedthereby in advance of ti e can over the position at which it is to beapplied to the latter'so that as the c'an'reaches the cover rece ivingposition the cover may be applied thereto. The means by which this isaccomplished includes a cover applying guide section 60 which is mountedat its inner end for pivotal movement upon pins 61 suitahiy mounted inthe frame of the machine. The guidesec'tion 60 is arranged to receive atits pivoted end the can cover as it is discharged fromjthe cleaningmachine at about he same time that the can therefor is being discharged.The cover applying guide section, as best show'n'in Figures 7 and 8 iscomposed of track or bar 62 upon which the cover may roll along its sidetoward the discharge end of the guide section and guide rods 63, 64:, 65and 66, the said bar 62 and rods being supported by side frames 62a todelimit a pas s'agewayfor the cover. At its outer end the guide rod 63is bent inwardly as at 8804 as is also the outer end of the bar 62.However, the angle at which the bent portion 63a is bent inwardly isgreater than theangle at which the bent portion of the bar 62 is bentand hence the two bent portions converge toward their outer ends. As therod 63 is a substantial distance above the bar '62, the bent port'ion63a acting against the flange of the cover tips the latter in thedirection of the top guide rod 65, it being noted that this rod as wellas the lower rod 66, is bent'inwardly so as to increase the width of thepassageway at this point to accommodate the cover as it is tipped to anupright position; The cover in its upright position is supported by itsflange upon the parallel terminal portions 68 of a rod 67 a the saidterminal portions preterably being inclined upwardly at a'slight angleaway from the pivoted end of the section 60. In the embodimentillustrated, one or" the said terminal portions is'connected to the bar62 while the other terminal portion is connected to the ends of theguide rods 65 and 66. Be yond the supporting terminal portions 68, therod 67 is bent to form an opening through which the flange or head ofthe cover may pass as it moves off the said supporting terminalportions. It will thus be apparent that the cover which is dischargedfrom the cleaning machine from the cover guide 19 may roll downthepassageway provided by the bar In accordance withthe invention,the coverissupported in advance of the can aboveits mouth andas the can reachesthe cover receiving position thecover is lowered into the mouth'of thecan. The pivoted cover apply ing guides action 60, is therefore,connected 2 by rod '58 toa crank 7 i which is carried'by a transverselyextending shaft 75. A. second crank '26 is iiizedt'othis shattadjacentits opposite end and-the said crank is connected by a rod '37 to'thelowerend'of the. lever 42; The'rod 73' as best shown in 'Fi'gnre'2,isconiected to the'outer end of the pivoted cover applyingguide sectionby a fork-shaped c2:- tension78. This extension provides a lost motionconnccti in between the rod 73 and pin 79 which eXtends'fr-oin the coverguide section. At the limit of its upward movement the cover applyingsection is preferably inclined slightly downwardly in thedir'ection ofthe cover applying position. The rod 'E3 is actuated to lower theouter'end ofthe cover appiying guide section and hence the cover carriedthereby toward the plane in which the mouth of the can is moving so thatas the canreaches the cover receiving position its'cover is lowered intothe mouth of the can in the manner shown in Fig. In this position, theterminal portions 68 of the rod 67 which normally support the cover restupon the lip of the can. It is to be noted that r the rod 73 is loweredto such extent that thepin 79 is intermediate the ends of theslot'formed by the extension 78 and that the free end of the pivotedcover applying giiid e section rests upon the can. As the c s advancedfurthergthe free end of the said section continues to lower while thecover moves out of the opening 70 against the action of the swinginggate'Zl. v

The lost motion connection between rod 73 and pivoted cover applyingsection is desirable as it enables the delivery mechanism to applycovers to cans of different sizes. Where covers are to be applied tocans of iic uniform size, the rod 6'? may be formed with ,7

extending pins 6% which engage angle'sto'p members 6864 to limit'thedownward movementof the free end of the cover appiying guide section.

The delivery mechanisn 7 in operation, adapted to' receive a can and itscover at substantially the same time, 'atwhic'h time the 7 side member29 of the troughis "arranged to co-operate with its companion sidemember 26'to arrest the can as it'fa'lls to a substantially horizontalposition. The cover apply tion, the combination of ing guide section atthis time is supported at the upper limit of its range of movement bythe rod 73. It will be noted, at this point, that the rod 73 isconnected as heretofore described. to the lower end of the lever 4:2 andthat the link 34 by which the pivoted side member 29 is actuated by theguide block 36 is connected to the upper end of the lever 42. Thusduring the interval that the can is supported in a substantiallyhorizontal position, the cover applying guide section remains stationaryand the cov .r therein may or may not roll toward the discharge opening70, this, of course, depending upon the angle of inclination of the saidsection when the cover enters it. However, as the lever 42 is actuatedto pivot the free end of the side member 29 of the reversing trough awayfrom the fixed side member, the outer end of the cover applying guidesection is lowered and the cover passes the can as it rolls by gravitydown the bar 62 to come to rest in an upright position upon the supports68. In the meantime, the can has been Lip-ended and as it moves towardthe position at which it is to receive its cover, the cover is beinglowered toward the plane in which the mouth of the can is moving. Theparts of the mechanism are so co-ordinated that as the can reaches thecover receiving position its cover is lowered into its mouth, the coversupports 68 coming to rest upon the lip of the can in the mannerdescribed while the rod 73 continues to move downwardly a shortdistance. Thus, as the can continues to advance, the end of the coverapplying guide section continues to lower and the cover is moved throughthe opening against the action of the swinging gate. After the can coverhas been applied, the cover applying guide section moves upwardly, itbeing understood that the pivoted side 29 of the reversing trough has inthe meantime been moved to condition the trough for receiving the nextsucceeding can, whereupon the cycle of operations described is repeated.
